Útihúsgögnin eru á veröndinni.

Because Icelandic makes very heavy use of compound nouns.

Here, útihúsgögnin is built from:

• úti = outside / outdoor
• húsgögn = furniture
• -in = the definite article the

So Icelandic packs the idea into one word instead of writing something more separate like English outdoor furniture.

Because the subject, útihúsgögnin, is grammatically plural, so the verb vera (to be) has to agree with it.

• er = is (singular)
• eru = are (plural)

So:

• Borðið er... = The table is...
• Stólarnir eru... = The chairs are...
• Útihúsgögnin eru... = The outdoor furniture are... grammatically, even though English would normally say is

This feels strange to English speakers because English furniture is singular/uncountable, but Icelandic treats húsgögn as plural.

Yes. Húsgögn is one of those Icelandic words that is grammatically plural, even when English uses a singular mass noun.

So Icelandic says:

• húsgögnin eru ný = the furniture is new

Even though the most natural English translation uses singular is, Icelandic grammar still uses plural agreement.

This is very common for learners to notice, because the grammar and the natural English translation do not match exactly.

It is the definite article, meaning the.

In Icelandic, the is usually attached to the end of the noun instead of being a separate word.

So:

• útihúsgögn = outdoor furniture
• útihúsgögnin = the outdoor furniture

English uses a separate word (the), but Icelandic usually adds it as a suffix.

Because veröndinni means the veranda / the porch / the patio in the dative singular definite form.

Breaking it down:

• verönd = veranda, porch, patio
• -inni = the ending showing the
  • the correct case ending here

So veröndinni is not just the basic noun. It is the form required by the grammar of the sentence.

The preposition á can take different cases depending on meaning.

A very useful rule is:

• location / being somewhere → usually dative
• motion toward / onto somewhere → usually accusative

Here the sentence describes location:

• the outdoor furniture is on the veranda

So Icelandic uses the dative:

• á veröndinni

Compare:

• Útihúsgögnin eru á veröndinni. = The outdoor furniture is on the veranda.
• Þau setja útihúsgögnin á veröndina. = They put the outdoor furniture onto the veranda.

So:

• á veröndinni = on the veranda already there
• á veröndina = onto the veranda

The dictionary form is verönd.

That is the nominative singular indefinite form, the form you would usually look up in a dictionary.

In this sentence, it appears as veröndinni because it is:

• singular
• definite (the)
• dative (after á for location)

Yes, Icelandic word order is somewhat flexible, though not completely free.

The neutral order here is:

• Útihúsgögnin eru á veröndinni.

But you could also say:

• Á veröndinni eru útihúsgögnin.

That version puts more emphasis on the location: On the veranda is where the outdoor furniture is.

One important thing to remember is that Icelandic often follows a verb-second pattern, so if something other than the subject comes first, the verb usually still stays in second position.

A few helpful pronunciation notes:

• ú in Úti is roughly like oo in food, but shorter and tenser
• ö in gögnin and veröndinni is somewhat like German ö or a rounded vowel not found exactly in standard English
• ð is like the th in this, not the th in thin

Very rough learner-friendly approximations:

• Úti ≈ OO-ti
• eru ≈ EH-ru
• veröndinni ≈ VEH-rund-in-ni (very approximate)

The exact Icelandic vowels are worth practicing with audio, because English spelling approximations only go so far.

It can depend on context. Verönd often corresponds to things English might call:

• veranda
• porch
• patio
• sometimes deck or a similar outdoor sitting area, depending on the situation

So even if the Icelandic word is the same, the best English translation may change depending on what kind of outdoor space is being described.
